ABB 1SDA050446R1 Moulded Case Circuit Breaker - IEC947-2

Feature → Business Impact → Application: The 4P design and 160 A rated current enable simultaneous protection of all three phases and neutral inIsomax S3 distribution boards, reducing coordination errors and improving reliability in motor and process lines. This translates to lower fault escalation, faster service restoration, and measurable uptime gains in manufacturing lines that demand continuous operation. The TadjM10 release type delivers precise, calibrated tripping, supporting selective protection and easier maintenance planning for complex switchgear assemblies in packaging, metals, or chemical processing. With a rated operational voltage of 690 V AC and an Icu up to 20 kA at this voltage (and up to 85 kA at lower voltages), designers can safely specify this MCCB for medium- and high-energy systems, improving overall protection margins. The unit’s 8 kV impulse withstand and 3000 V test voltage provide robust insulation integrity under demanding industrial conditions, helping to minimize nuisance trips and ensure regulatory compliance. The RoHS information (1SDL000199R0001) and CE declaration (1SDL000160R0017) support sustainable procurement and traceability, while the compact footprint (178 mm wide, 233 mm high, 103.5 mm deep) and 3.5 kg net weight simplify panel mounting and retrofits in limited spaces. In practice, installers gain faster commissioning, safer wiring with front-terminals, and predictable performance during fault events in Isomax S3 installations, with enough headroom for future expansion and easier lifecycle maintenance.
